For example, a different number or different size of gears, and belt transmission or friction transmission, etc., than the present embodiment.

Three specific embodiments are provided.

In the first embodiment, the agitator frame 13 connects the first transmission assembly 2 and the second transmission assembly 3.

In this embodiment, the first transmission assembly 2 transmits power to the detected member 4 through the stirring frame 13 and the second transmission assembly 3, so that a transmission structure penetrating the box body 1 is not required to be additionally arranged, the structure of the processing box is simple, and the production cost is reduced.

As shown in fig. 1, a first end 11 of the box 1 is provided with a first protecting cover 5 for protecting the first transmission assembly 2, a second end 12 of the box 1 is provided with a second protecting cover 6 for protecting the second transmission assembly 3 and the detected piece 4, and an opening for the detected piece 4 to partially extend is formed in the second protecting cover 6. The first protecting cover 5 and the second protecting cover 6 can be fixed on the box body in a screw connection mode, and can also be fixed in a buckle connection mode. As shown in fig. 2, the cartridge 1 is provided with a handle 15, and the process cartridge can be easily loaded into the image forming apparatus by grasping the handle 15.

In a specific embodiment, as shown in fig. 4, the second end 12 is provided with a limit groove 122, and as shown in fig. 5 and 6, the second transmission assembly 3 includes: the shaft sleeve 30 and the first driving wheel 31, the shaft sleeve 30 is sleeved on the stirring frame 13 and can rotate along with the stirring frame 13, as shown in fig. 8, the shaft sleeve 30 is provided with a limiting protrusion 301a, the limiting protrusion 301a can extend into the limiting groove 122, the first driving wheel 31 is connected with the shaft sleeve 30 and can rotate along with the shaft sleeve 30, and the first driving wheel 31 can drive the detected piece 4 to move.

After the shaft sleeve 30 rotates with the stirring frame 13 by a set angle, the shaft sleeve 30 can move in the axial direction away from the first driving wheel 31, so that the limit protrusion 301a extends into the limit groove 122 to limit the rotation of the shaft sleeve 30 with the stirring frame 13.

In this embodiment, as shown in fig. 6 and 8, after the process cartridge is loaded into the image forming apparatus, the image forming apparatus drives the agitator 13 to rotate through the first transmission assembly 2, at this time, the shaft sleeve 30 can rotate with the agitator 13, the limit projection 301a can be aligned with the limit groove 122 before the shaft sleeve 30 rotates more than one revolution, the limit projection 301a extends into the limit groove 122, and the rotation of the shaft sleeve 30 is limited by the limit groove 122. Therefore, by setting the angular relationship between the projection of the line between the limit protrusion 301a and the axis of the stirring frame 13 along the first direction X and the projection of the line between the limit groove 122 and the axis of the stirring frame 13 along the first direction X, the rotation angle of the shaft sleeve 30 and the first driving wheel 31 along with the stirring frame 13 can be controlled, so as to further control the movement of the detected member 4, and realize the triggering of the detection assembly in the image forming apparatus. If the process cartridge is used, the limit projection 301a must extend into the limit groove 122, and the detected member 4 cannot trigger the detecting assembly, so that the presence or absence of the process cartridge can be detected by the detected member 4.

In a specific embodiment, as shown in fig. 7, the stirring frame 13 is provided with a first transmission protrusion 131 near one end of the second transmission assembly 3; as shown in fig. 9, the inner wall of the sleeve 30 is provided with a second driving protrusion 301c, and as shown in fig. 10, the first driving protrusion 131 can abut against the second driving protrusion 301c to drive the sleeve 30 to rotate.

In the present embodiment, as shown in fig. 10, before the limit projection 301a does not extend into the limit groove 122, when the stirring frame 13 rotates, the first transmission projection 131 abuts against the second transmission projection 301c, so as to push the shaft sleeve 30 to rotate; when the limit protrusion 301a extends into the limit groove 122, the shaft sleeve 30 moves in the first direction X relative to the limit protrusion 301a when not extending into the limit groove 122, and the first transmission protrusion 131 cannot abut against the second transmission protrusion 301c, so that the stirring frame 13 cannot drive the shaft sleeve 30 to rotate, and the shaft sleeve 30 cannot limit the rotation of the stirring frame 13, thereby ensuring that the processing box can work normally.

In a specific embodiment, as shown in fig. 9, the inner wall of the sleeve 30 is provided with a limit collar 301b; as shown in fig. 6, the second transmission assembly 3 further includes a first elastic member 32, one end of the first elastic member 32 abuts against the first transmission wheel 31, and the other end abuts against the limiting convex ring 301 b. When the limit protrusion 301a is aligned with the limit groove 122, the first elastic member 32 can drive the shaft sleeve 30 to move along the axial direction away from the first driving wheel 31, so that the first limit protrusion 301a extends into the limit groove 122.

In this embodiment, as shown in fig. 6, before the limit protrusion 301a does not extend into the limit groove 122, the first elastic member 32 is in a compressed state under the action of the first driving wheel 31 and the limit collar 301b, so when the limit protrusion 301a is aligned with the limit groove 122, the first elastic member 32 can drive the shaft sleeve 30 to move in a direction away from the first driving wheel 31 in the axial direction, thereby disconnecting the transmission of the stirring frame 13 to the shaft sleeve 30.

Specifically, the projection of the limiting convex ring 301b in the first direction X is in an arc shape, the limiting convex ring 301b is close to the first driving wheel 31 relative to the second driving protrusion 301c, and the projections of the limiting convex ring 301b and the second driving protrusion 301c in the first direction X are not overlapped, so that the production and processing of the shaft sleeve 30 are facilitated. The distance between the limit collar 301b and the second transmission protrusion 301c is greater than the length of the first transmission protrusion 131 in the first direction X, so that when the limit protrusion 301a extends into the limit groove 122, the first transmission protrusion 131 can be located between the limit collar 301b and the second transmission protrusion 301c, and the first transmission protrusion 131 is not in contact with the shaft sleeve 30, thereby ensuring that the stirring frame 13 can still rotate smoothly. The first elastic member 32 may be a spring, preferably a compression spring.

In a specific embodiment, as shown in fig. 4, the second end 12 is provided with a recess 121, the limiting groove 122 is disposed on the bottom wall of the recess 121, the bottom wall of the recess 121 is further provided with a through hole 123, and the shape of the through hole 123 is set corresponding to the shape of the stirring rack 13 and the first transmission protrusion 131 on the stirring rack 13, so that one end of the stirring rack 13 near the second end 12 can extend into the recess 121 through the through hole 123.

Since the diameter of the body 301 is smaller than the diameter of the recess 121, the sleeve 30 can rotate with respect to the recess 121.

As shown in fig. 11 and 13, a third transmission protrusion 311 is disposed on a side of the first transmission wheel 31 facing the sleeve 30, the third transmission protrusion 311 passes through the limit recess 302a to be abutted with an end surface of the recess 121, and a length of the third transmission protrusion 311 is greater than a thickness of the extension 302 along an extending direction of the third transmission protrusion 311.

In this embodiment, since the third transmission protrusion 311 passes through the limit recess 302a, when the sleeve 30 rotates, the first transmission wheel 31 rotates along with the sleeve 30, so that the transmission of the sleeve 30 to the first transmission wheel 31 is achieved. Meanwhile, the length of the third transmission protrusion 311 is greater than the thickness of the extension portion 302, so that the shaft sleeve 30 can move along the first direction X relative to the third transmission protrusion 311, thereby realizing the transmission connection of the shaft sleeve 30 and the stirring frame 13 or releasing the transmission connection of the shaft sleeve 30 and the stirring frame 13.

Specifically, as shown in fig. 11, the number of the third transmission protrusions 311 is preferably two, and the two third transmission protrusions 311 are symmetrically disposed on the first transmission wheel 31. As shown in fig. 9, the limit recesses 302a are disposed corresponding to the third driving protrusions 311, so the number of limit recesses 302a is also preferably two, and the two limit recesses 302a are symmetrically disposed on the extension portion 302. The first driving wheel 31 is further provided with a first mounting hole 313, one end, close to the second end 12, of the stirring frame 13 sequentially passes through the through hole 123, the shaft sleeve 30 and the first mounting hole 313, the first mounting hole 313 is a countersunk hole, the connecting piece 132 extends into the first mounting hole 313 from the direction opposite to the direction that the stirring frame 13 extends into the first mounting hole 313, the shaft sleeve 30 and the first driving wheel 31 are prevented from being separated from the stirring frame 13, the first driving wheel 31 is in clearance fit with the stirring frame 13, the first driving wheel 31 cannot block rotation of the stirring frame 13, and the stirring frame 13 cannot block rotation of the first driving wheel 31. The connecting member 132 may be a screw, etc., and the end of the stirring frame 13 near the second end 12 may be provided with a threaded hole.

In a specific embodiment, as shown in fig. 12, a fourth transmission protrusion 312 is provided on a side of the first transmission wheel 31 facing the inspected member 4. As shown in fig. 14, the second end 12 is provided with a rotation shaft 71 intersecting with the axis of the second transmission assembly 3, the axis of the rotation shaft 71 extends in the second direction Y, and the inspected member 4 is rotatably connected to the rotation shaft 71.

The fourth transmission protrusion 312 extends into the connection hole 332 to realize the rotational connection between the first transmission wheel 31 and the first link 33; the connection post 331 extends into the through hole of the connection post 331, so that the first link 33 is rotatably connected to the slide plate 34, and the abutting portion 342 can abut against the contact end 41 of the workpiece 4.

As shown in fig. 18 and 19, during the rotation of the first link 33, the slide plate 34 is capable of sliding in the second direction Y with respect to the second end 12 and abuts against the contact end 41 to drive the rotation of the inspected member 4. Defining that the abutment 342 is not in contact with the contact end 41, the detected member 4 is in the first state (as shown in fig. 18), and the detection end 42 cannot trigger the detection component in the image forming apparatus; when the abutting portion 342 is defined to be in contact with the contact end 41, the detected member 4 is in the second state (as shown in fig. 19), and the detection end 42 triggers the detection member in the image forming apparatus.

Specifically, as shown in fig. 15 and 17, the surfaces of the abutting portions 342 abutting against the contact ends 41 are inclined, so that the driving of the contact ends 41 by the abutting portions 342 is smoother.

As shown in fig. 20, a positioning cover 7 is detachably connected to the second end 12 of the box body 1, a sliding groove 74 extending along the second direction Y is further formed in the positioning cover 7, and a body 341 of the sliding plate 34 can extend into the sliding groove 74 and slide along the sliding groove 74, and the sliding groove 74 plays a role in guiding the sliding plate 34 and limiting the sliding plate 34 to slide within a set range. The second protecting cover 6 is detachably provided with a third protecting cover 8, and the third protecting cover 8 covers the sliding plate 34 to prevent the movement of the sliding plate 34 from being disturbed by the outside.

As shown in fig. 14, 15 and 20, the contact end 41 of the detected member 4 is provided with a first limit post 412, the positioning cover 7 is provided with a second limit post 75, and a second elastic member 76 is provided between the first limit post 412 and the second limit post 75. When the detected member 4 is in the second state, the second elastic member 76 is compressed, and has a tendency to return the detected member 4 to the first state, so that the detected member 4 is switched from the second state to the first state.

In this embodiment, to achieve different times of triggering of the detection assembly in the image forming apparatus, a plurality of abutment portions 342 may be provided on the slide plate 34 or a plurality of contact ends 41 or other intermediate transmission members may be provided on the detected member 4 to adapt to process cartridges having various models.

Taking the example in which two abutting portions 342 are provided on the sliding plate 34 as an example, when the image forming apparatus drives the process cartridge through the power receiving portion 23 and makes the sliding plate 34 slide along the second direction Y, the first abutting portion 342 approaches the contact end 41, and after abutting against the contact end 41, drives the detecting end 42 to rotate to the second state, the detected member 4 triggers the detecting assembly once, the sliding plate 34 continues to slide until the first abutting portion 342 is separated from the contact end 41, at this time, the detected member 4 returns to the first state under the action of the second elastic member 76, and then the second abutting portion 342 abuts against the contact end 41 and drives the detecting end 42 to rotate to the second state, and the detected member 4 triggers the detecting assembly a second time. Therefore, the structure in the present embodiment can trigger the detection member a plurality of times, thereby enabling the image forming apparatus to detect the new and old or model of the process cartridge according to the number of times the detection member is triggered. If the detecting member 4 fails to trigger the detecting assembly, the process cartridge is judged to be an old process cartridge.

Meanwhile, the abutting portion 342 in the present embodiment may also be in direct contact with a detection member in the image forming apparatus, or in indirect contact with a detection member in the image forming apparatus through a different intermediate transmission member.
